Radio Tech Could Halve Bandwidth Needs

According to an article from The Register, a team from Stanford University has patented technology that could halve the bandwidth that a mobile provider needs.

Operating under the name Kumu Networks, they are showcasing tech which they claim would exactly double throughput. Radio equipment (such as mobile phones) would be able to send and receive on the same frequency through a process similar to noise-cancelling headphones; by knowing what a base station is transmitting it can cancel out the information from the very faint signal it receives.

    Agreed, with SSB there cannot be 2 continuous signals sharing the same bandwidth. That stated, since a typical SSB signal takes ~half the bandwidth of an equivalent AM signal, it does allow for 2 different SSB channels in the space of one AM channel.

    While the isolation is not always great, with SSB it is certainly possible to have two simultaneous conversations, one on the upper sideband and one on the lower.
